Leachate Treatment System Design and Permitting

SCS staff has been involved in design of leachate treatment systems in many regions of the country.  SCS has employed various technologies including extended aeration, nitrification/denitrification, activated carbon, constructed wetlands, and chemical treatment to address site-specific leachate characteristics and site conditions.  The selection of a treatment approach is dependent on many variables, including site location, leachate quality and quantity, availability of utilities, discharge limitations, and environmental regulations.  Because of variability in leachate quality, treatment approaches must be evaluated on a case by case basis. 

Several relevant projects are listed below:

Fort Gordon, Georgia.  Design, permitting, and construction of a metals pretreatment facility to treat leachate from the 17^th Street Landfill, Fort Gordon, Georgia.

Hillsborough County, Florida.  Feasibility study, design, permitting, and construction for 60,000 gallon per day (gpd) leachate treatment and reclamation facility, Southeast Landfill, Hillsborough County, Florida.  The treatment facility includes 575,000-gallon storage tanks, powdered-carbon activated sludge, nitrification/ denitrification, pH adjustment, and chlorination treatment units, and spray irrigation of treated effluent.

Portland, Maine.  Design, permitting, and construction of a wetlands treatment system for contaminated groundwater beneath the Regional Waste System, closed Balefills.  The system included a multiple stage treatment system to treat specific contaminants in the groundwater.

Volusia County, Florida. Design, permitting, and construction for major modifications to the leachate management systems at the Tomoka Farms Road Landfill, including new 5 million gallon capacity, double-lined, leachate storage basins recirculation/ evaporation system and new conveyance systems.
